Anatomy and Classification of Aortic Dissection

2 Aortic dissection is the most common disorder of the aorta that brings a patient to the emergency room. If left untreated, 75 percent of sufferers die in the first two weeks and 90 percent die in the first three months. Preventing the aorta from rupturing or from blocking blood supply to other areas of the body are the primary treatment goals of any thoracic aortic dissection. Anatomy and Classification of Aortic Dissection False lumen True lumen Intimal tears Type-A aortic dissections involve the ascending portion of the aorta and typically require emergency cardiothoracic surgery to avoid acute lethal complications. This may involve the replacement of the ascending aorta with a synthetic graft and the per-aortic placement of a DJUMBODIS bare stent in the aortic arch as an alternative to a time-consuming and complicated total arch replacement and to avoid a post surgical migration of the disease. Type-B dissections involve the descending aorta and in some 25% of cases the aortic arch. A Type-B dissection may initially be stabilized medically, however the disease often progresses leading to a more challenging situation with significantly higher morbidity and mortality risks associated. In order to limit the progression of the disease and to manage potential complications with blood flow to the lower body, an interventional procedure is recommended and increasingly popular.

3 DJUMBODIS ENDOPROTHESIS The chief purpose of the DJUMBODIS is to rejoin the dissected tissue layers, thrombosis of the false lumen and restoration of the aortic wall without obstructing collateral blood flow to other areas of the body. TYPE - A TYPE - B The pre-mounted DJUMBODIS is a bare stent endoprosthesis made of 316L biocompatible stainless steel. Delivered via a unique, low profile, low pressure and highly compliant balloon catheter, the DJUMBODIS conforms to the aorta and retains its new shape as the balloon inflates and deflates. The DJUMBODIS is available in 4cm, 9cm, 14cm, 19cm and 24cm nominal lengths. Multiple DJUMBODIS can be deployed to cover a larger extent of the aorta.

4 Type A and Type B Acute and Chronic Treatment Surgical and Percutaneous Extend your possibilities The DJUMBODIS can be expanded up to a maximum of 45mm. In doing so the DJUMBODIS rejoins the dissected tissue layers, thromboses the false and reopens the true lumen and aligns itself to the actual diameter and shape of the patient s aorta, like a made-to-measure prosthesis. The DJUMBODIS is designed and approved to treat aortic dissections. It allows obliteration of the false lumen and contributes to aortic reinforcement and restoration. The balloon compliance and dedicated design of the DJUMBODIS allows the prosthesis to follow the shape of the aorta and ensures stability and permanent anchoring. The openwork, chain link design of the DJUMBODIS allows for continued blood flow to collateral arteries without the need for fenestration and de-branching. Surgical DJUMBODIS Dissection System Type A dissection Each DJUMBODIS is accompanied with a supplementary delivery catheter with a balloon of 4cm length.

5 Percutaneous DJUMBODIS Dissection System Type B dissection Each DJUMBODIS is accompanied with a supplementary delivery catheter with a balloon of 4cm length. Usable with guide wire The small profile of the pre-mounted Djumbodis is compatible with a 20F access and enhances easy delivery and potentially reduces femoral and iliac complications. DJUMBODIS: Morphometric Bare Stent Endoprosthesis

6 The DJUMBODIS bare stent endoprosthesis is safe and easy to handle, allowing early treatment of the dissection and minimizing the significant risks and later treatment challenges otherwise associated with a progressing disease. With its deployment mechanism and open link design, the Djumbodis effectively obliterates the false lumen, conforming well to the aortic wall and without obstructing collateral blood flow. The DJUMBODIS is allowing patients to lead a normal life following early treatment of the dissection. The DJUMBODIS Dissection System thromboses the false lumen and allows the aorta to heal within six weeks from implantation. The healing permits reinforcement of the native aorta, resulting in a better solution than replacing it by a prosthesis. The treatment with the DJUMBODIS has positive pathophysiological effects and makes it possible to eliminate the false lumen where deployed. It has not caused any increase in morbidity or mortality. jaihk éd Photos Julien Ayache // Impression Cgraph Saint Côme Chirurgie 185 Chemin du Vallon de l Oriol Marseille France Tel : 33(0) Fax : 33(0) saintcome@inter.net Your local contact
